Sample from industry effluent consists of various metal like lead, zinc, copper, silver, mercury etc. The growth of microorganisms is affected by various factors like temperature, ph, salinity etc. In some cases there are some  microorganisms which can tolerate the presence of metal like lead, zinc, copper, silver, mercury etc, Presence of these metal is analysed  by atomic absorption spectrometry method, present study deals with  isolation of Serratia liquefaciens is done by various biochemical characteristics, various parameter analysis, culturing of Serratia   liquefaciens in the bacterial growth medium which consist of artificially supplemented with metal. From the study, it is confirmed that Serratia liquefaciens  is present in the polluted water where metal dust persists in the effluent sample. Serratia   liquefaciens were resistant to metal and these microorganisms are further encouraged to degrade metal in the sample
